the battery icon in the system tray of the Taskbar to confi rm the

Battery Usage Time Information
A battery is an expendable supply, so when using it over a long
time, the capacity/battery life is shortened. If the battery life is
reduced to under half of its initial time, we recommend purchasing
a new battery.
When not using the battery for a long time, store the battery after
charging it to 30-40% of its capacity. This extends the battery life
time.
Extending the Battery Usage Time
Decreasing the LCD Brightness
Press the
+
keys on the keyboard to decrease the LCD
brightness to extend the battery usage time.
Using the power management program
This program helps you use the battery more effi ciently
and supports the power mode optimized for the operating
environment.
